Animal
Animals are multicellular, eukaryotic organisms in the Biology, biological Kingdom (biology), kingdom Animalia (). With few exceptions, animals heterotroph, consume organic material, Cellular respiration#Aerobic respiration, breathe oxygen, have myocytes and are motility, able to move, can reproduce sexually, and grow from a hollow sphere of Cell (biology), cells, the blastula, during embryonic development. Animals form a clade, meaning that they arose from a single common ancestor. Over 1.5 million extant taxon, living animal species have been species description, described, of which around 1.05 million are insects, over 85,000 are molluscs, and around 65,000 are vertebrates. It has been estimated there are as many as 7.77 million animal species on Earth. Animal body lengths range from to . They have complex ecologies and biological interaction, interactions with each other and their environments, forming intricate food webs. The scientific study of animals is known as ...

Arthropod
Arthropods ( ) are invertebrates in the phylum Arthropoda. They possess an arthropod exoskeleton, exoskeleton with a cuticle made of chitin, often Mineralization (biology), mineralised with calcium carbonate, a body with differentiated (Metamerism (biology), metameric) Segmentation (biology), segments, and paired jointed appendages. In order to keep growing, they must go through stages of moulting, a process by which they shed their exoskeleton to reveal a new one. They form an extremely diverse group of up to ten million species. Haemolymph is the analogue of blood for most arthropods. An arthropod has an open circulatory system, with a body cavity called a haemocoel through which haemolymph circulates to the interior Organ (anatomy), organs. Like their exteriors, the internal organs of arthropods are generally built of repeated segments. They have ladder-like nervous systems, with paired Anatomical terms of location#Dorsal and ventral, ventral Ventral nerve cord, nerve cord ...

Insect
Insects (from Latin ') are Hexapoda, hexapod invertebrates of the class (biology), class Insecta. They are the largest group within the arthropod phylum. Insects have a chitinous exoskeleton, a three-part body (Insect morphology#Head, head, Thorax (insect anatomy), thorax and abdomen (insect anatomy), abdomen), three pairs of jointed Arthropod leg, legs, compound eyes, and a pair of antenna (biology), antennae. Insects are the most diverse group of animals, with more than a million described species; they represent more than half of all animal species. The insect nervous system consists of a insect brain, brain and a ventral nerve cord. Most insects reproduce Oviparous, by laying eggs.

Beetle
Beetles are insects that form the Taxonomic rank, order Coleoptera (), in the superorder Holometabola. Their front pair of wings are hardened into wing-cases, elytra, distinguishing them from most other insects. The Coleoptera, with about 400,000 described species, is the largest of all orders, constituting almost 40% of described arthropods and 25% of all known animal species; new species are discovered frequently, with estimates suggesting that there are between 0.9 and 2.1 million total species. However, the number of beetle species is challenged by the number of species in Fly, dipterans (flies) and hymenopterans (wasps). Found in almost every habitat except the sea and the polar regions, they interact with their ecosystems in several ways: beetles often feed on plants and fungi, break down animal and plant debris, and eat other invertebrates. Some species are serious agricultural pests, such as the Colorado potato beetle, while others such as Coccinellidae (ladybirds or ...

Polyphaga
Polyphaga is the largest and most diverse suborder of beetles. It comprises 144 families in 16 superfamilies, and displays an enormous variety of specialization and adaptation, with over 350,000 described species, or approximately 90% of the beetle species discovered thus far. Key characteristics of Polyphaga are that the hind coxa (base of the leg) does not divide the first and second abdominal/ventral plates which are known as sternites. Also, the notopleural suture (found under the pronotal shield) is not present. Etymology The name of ''polyphaga'' is derived from two Greek words: , meaning 'many', and , meaning 'to eat', so the suborder is called the “eaters of many things”. Classification The five main infraorders are: * Bostrichiformia — including furniture beetles and skin beetles * Cucujiformia — includes lady beetles, longhorn beetles, weevils, checkered beetles and leaf beetles * Elateriformia — includes click beetle Elateridae or clic ...

Scarabaeoidea
Scarabaeoidea is a superfamily of beetles, the only subgroup of the infraorder Scarabaeiformia. Around 35,000 species are placed in this superfamily and some 200 new species are described each year. Some of its constituent families are undergoing revision, and the family list below is provisional. This superfamily includes some of the largest beetles extant today, including rhinoceros beetles (Dynastinae), especially the Hercules beetle (''Dynastes hercules'') and the Goliath beetles (''Goliathus'' sp.). The oldest confirmed member of the group is the extinct genus '' Alloioscarabaeus'' from the Middle Jurassic period Jiulongshan Formation of Inner Mongolia, China.

Hybosoridae
Hybosoridae, sometimes known as the scavenger scarab beetles, is a family of Scarabaeiformia, scarabaeiform beetles. The >600 species in 78 extant genera occur widely in the tropics, but little is known of their biology. Hybosorids are small, 5–7 mm in length and oval in shape. Color ranges from a glossy light brown to black. They are distinctive for their large Mandible (insect mouthpart), mandibles and Insect mouthparts#Labrum, labrum, and their 10-segmented antennae, in which the 8th antennomere of the club is deeply grooved and occupied by the 9th and 10th antennomeres. The legs have prominent spurs. The larvae have the C-shape and creamy white appearance typical of the scarabaeiforms. The 4-segmented legs are well-developed; the front legs are used to stridulate by rubbing against the margin of the epipharynx, a habit unique to this family. Adults are known to feed on invertebrate and vertebrate carrion, with some found in dung. Larvae have been found in decomposing ...
